We're looking at them very, very seriously. I've gone to all of the folks in charge of the various agencies and we're -- I've actually called the justice department to look into the leaks. Those are criminal leaks. Let's bring in our legal analyst Dan Abrams and Brad Garrett. You heard the president calling these leaks criminal. Is that the case? They could be. Certainly. There are a lot of statutes that you can use to prosecute people for sharing information related to the national defense. Doesn't even have to be officially classified information. Then you've got the possibility of classified information. You've got a whole host of statutes to use. If you want to and want to dig in to figure out who did it and whether they should be prosecuted. It is confusing because we heard president trump say the leaks are real but the news is fake. How do those two things co-exist? They don't. Either there are people with access to national defense information or classified information that are improperly sharing this accurate information or the immediate were is making this stuff up, right? If the media is making it up or if these people who are in government are taking the media for a ride what do you investigate? You're investigating nonsense so either it's real and it's frightening to the president and it shouldn't be happening because this is important information that's being shared or we in the media are supposedly just making this stuff up in which case there's nothing to investigate. Let's talk about the investigation. Brad, president trump is saying he is having the justice department look into these leaks. How difficult? What is it like to catch leakers? The first thing you have to do is figure out if the information leaked is actually classified. Many times the press only get a small portion so that has to be vetted first and then look at the number of people who had potential access to that information. I will tell you, Amy, less than 50% are identified and virtually nobody ends up being prosecuted at the end of the day. All right. Brad Garrett, Dan Abrams, more to come. Thank you so much.
